srEcI'FIcArrIoN forming 15m of Letters Patent No. 655,360, dated August 14, 1906).. Application filed March 29, 1900. Serial No. 10,647. (No model.)

To all whom it maypmwern:

Be it known that we, J AMES FRASER, late inillmanager, residing at Dundee, in the county of Forfar, and J AMES GAv'iN FRASER,

engineer, and HUGH WALKER, carpenter,

tumbling or throwing-out weighted or spring.

actuated lever and fittings for throwing the rove or yarn to one side to clear it from the grip of the retaining-rollers, and so stop delivery of the rove without stopping the rollers when the roving breaks on its way to the flier or other twisting mechanism.

Referring to the drawings, whichform part of this specification, Figures 1 and 2 are respectively side sectional and front elevations of parts of a spinningunachine, showing the tumblingdever fitted in front of the retaining-rollers. Figs. 3 and 4 are respectively side sectional and front clevationsof parts of a spinning-machine, showing the tumbling-lever fitted behind the retainingrollers, while Figs. 5 and 6 are similar views illustrating another method of fitting the tumbling-lever behind the retaining-rollers.

Figs. 7 and 8 are similar views showing the tumbling-lever fitted between the retainingrollers.

As shown in Figs. 1 and 2, the tumbling or throwing-out lever a is pivoted on .the pin 1) on a bar 6, secured in front of the retainingrollers 0 cl, and isformed with a bent-over top part formed with an eye or loop (0 at its end and has a weight a secured on it. The tumbling-lever a rests against the stop e and is held up in a position slightly oif the perpendicular by the trigger or releasing rod f working through the guide g and secured by its lower end to the oscillating arm or lever h,

pivoted on the railt' of spinning-machine at j. This longoscillating arm 7L also carries the curved arm 75, on which is secured the hacklegill Z. The rove R passes through the eye a on its way tothe retaining-rolls c d, whence it passes over the rove-plate m to'the drawing-rollers 71 0 from which it passes to the flier orother twisting mechanism. lVhile the yarn remains unbroken it holds up the trigger-rodfin its stopping position'against the tumbling-lever a by pressing on the bent end lb of the arm h, connected to the trigger-rod f; but if the yarn breaks the trigger-rod f by the fall of the arm h is released and allowed ,to fall to release the tumbling-lever a, which as it falls to one side draws the rove R from between the retaining-rollers and so stops delivery. At the same time the hackle-gilll is moved forward to catch or interceptthe rove. W Vhen the spinner pulls the end h of the arm h forward and replaces the tumblinglever (t in its normal working position, the free end of the springf ,secured to the triggerrodf, rises over the stop-pin e and automatically upholds the rod f and lever a until the rove is again in running working order, when the arm h is restored to its normal working position,with its end h supported by the rove, the trigger-rod by the same actionbein g lowered till the end of the spring f falls below the stop-pin e. The spring is secured to the rodf in any suitable manner-for instance, by one of its ends passingthrough an opening in the rodand its free end is shown at in Figs.'1 and 3. This end while flexible is sufficiently st-iff to hold the rodf up by engaging the upper side of the stop-pin 6 when thespinner raises the rod.

As shown in Figs. 3 and 4, the tumbling or weighted throwing-out lever a, fitted behind the retaining-rollers o d, is bent to avoid contact with the back roller and is pivoted on the stud-pin 17, secured on the bracket 2' on the rail t' of spinning machine. The trigger rod or lever f is also bent and is pivoted on the stud-pin f and has its upper end f bent over hook shape toengage with and hold up the tumbling-lever a so long as the yarn remains unbroken. The lower end f of the triggerzoo,

lever h k The pressure of the rove on the bent end it of the arm It holds it back against the bent arm a which acts as a stop and prevents the eye h from acting on the angled arm f to shift the trigger-arm and release the tumbling-lever a. When the yarn breaks, the lever h h is allowed to fall sidewise, and by its eye it it acts on the angled arm f of the trigger-lever ff and by disengaging the hook partf allows the lever a to fall to one side and by sofalling draw the rove by its eye or loop a (or it may be simplya fork) from between the retaining-rolls c d. The hacklegill lat the same time moves sidewise with the'lever h 71 to intercept and catch the rove by its teeth. The hook f also temporarily sustains the tumbling-lever a while the spinner replaces the rove in running order.

As shown in Figs. 5 and 6, the tumblinglever a is fitted behind the retaining-rolls, but is released in a different manner. In this case the tumblinglever a is upheld while the yarn remains unbroken by the point of the trigger-rod f, which slides in a tube f secured to the bracket t", and has its lower end angled upward at F. When the yarn breaks, the lever 72. 71. acts by means of its eye k on the angled end f of the trigger-rod f, and drawingit down releases the tumblinglever a, which stops the delivery of the rove by drawing it from between the retainingrollers c d. While the spinner is replacing the rove the tumbling-lever a is temporarily upheld by the springf, (shown in Fig. 5,) the end of which rises over the lever 17. when the arm h is pulled to one side in an equivalent manner to the spring shown in Figs. 1 and 2 and falls below when the arm h is in normal working position. i

By another arrangement, as shown in Figs. 7 and 8, the tumbling-lever a is fitted between the retaining-rollers-in the space between the shafts carrying the same and is fulcrumed on the carrier-bar b, bolted to the bearing'bar b of spinning-machine, while the yarn remains unbroken, the weighted lever a, upheld by the trigger or slip rod f, passing through the guide 9 andsecured at its lower end to the arm h, pivoted atj, which carries the hacklegill Z and its supporting-arm 70. When the yarn breaks, the arm 7% falls back and the slip-rod f, secured to same, moves downward and releases the tumbling-lever a, which is caused by the weight a to fall to one side and draw, by means of its hook or, or it may be a fork the rove from between the retainingrollers c d. The'hackle-gill lat the same time moves forward to intercept the rove. While the spinner is replacing the rove the tumbling-lever a is temporarily upheld by the projection f on the trigger f, which by the forward pull of the arm his caused to rise above the bent upper part of the lever a and rest on it until the arm his placed in normal working position supported by the rove.

We have shown weights applied directly to the throw-out levers a; but it will be understood that the equivalent device--a spring may also be applied to give the same action as the weight.

Having now described our invention, What we claim as new, and desire to secure by Letters Patent, is-

1. In combination, a weighted tumbling throw-out lever, a sustaining or releasing trigger-rod engaging the throw-out lever, a hackle-gill, a lever carrying the same, said lever having an end 71. to engage the rove and hold the hackle-gill out of contact with the rove and a connection between said hacklegill lever and the trigger whereby when the rove breaks the hackle-gill lever will operate to withdraw the trigger and move the hacklegill into the path of the rove, substantially as described.

2. In combination, a weighted tumbling throw-out lever, a sustaining or releasing trigger-rod engaging the throw-out lever, a hackle-gill, a lever carrying the same, said lever having an end h to engage the rove and hold the hackle-gill out of contact with the rove and a connection between said hacklegill lever and the trigger whereby when the rove breaks the hackle-gill lever will operate to withdraw the trigger and move the hacklea gill into the path of the rove, and a springf carried by the trigger to hold the tumblinglever in position while the parts are being reset, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of the subscribing witnesses.
